Background
Model 551 is a CO Detector that Display CO Level between 10PPM
(Parts per Million) to 999PPM. The detector consists of one

time the unit is turned on or reset button is pressed in a non
alarm condition, the will test the entire circuit for
integrity. If the unit alarms, the unit can be silenced by

SELF TEST SEQUENCE AT STARTUP:
When you power up the Aero-551, you will notice the following test
sequence:
The screen will show the word “CO Guardian, short beep and current
time will display. Internally in the background, the system will
check the sensor for 30 seconds and all internal components. If any
components fail, the display will show the word “Failed” and the unit
must be returned for repair.
CARBON MONOXIDE LEVEL INDICATION:
DISPLAY : CO LEVEL
Aero 551 can detect Carbon Monoxide from as low as 10 PPM. Aero 551 will
trigger an alarm for CO long before the pilot / passengers can be affected
by exposure to CO.
The effect of CO level on the human body is linked to the duration of
exposure to CO. Our units are designed to set off CO alarms in progressively
shorter durations as the concentration of CO increases. The intention is to
prevent a false alarm when the CO level poses no danger, but at the same
time ensure full protection when the level starts becoming dangerous.

sound within 5 minutes if the CO level stays above 75 +/- 5 PPM. If the CO
level rises above 300 PPM, the alarm will trigger within one minute.
The alarm sequence for CO is:
4 short beeps from the buzzer and 4 flashes from the LED, and 4 beeps to the
